WMMWireless Multimedia (WMM) mode, which supports devices that meet the 
801.11e QBSS standard. WMM uses traffic priority based on the four 
ACs; Voice, Video, Best Effort, and Background. The higher the AC 
priority, the higher the probability that data is transmitted.
Check the Enable WMM Function box, the WMM parameters table...

Access Categories – WMM defines four access categories (ACs): voice, 
video, best effort, and background. These categories correspond to traffic 
priority levels and are mapped to IEEE 802.1D priority tags. The direct 
mapping of the four ACs to 802.1D priorities is specifically intended to 
facilitate inter operability with other wired network QoS policies. While 
the four ACs are specified for specific types of traffic, WMM allows the 
priority levels to be...

CWMin (Minimum Contention Window) – The initial upper limit of the 
random backoff wait time before wireless medium access can be 
attempted. The initial wait time is a random value between zero and the 
CWMin value. Specify the CWMin value in the range 0-15 microseconds. 
Note that the CWMin value must be equal or less than the CWMax value.

transmit queue has access to the wireless medium. When an AC queue is

WDSThe Router supports WDS (Wireless Distribution System). WDS enables 
one or more Access Points to rebroadcast received signals to extend 
range and reach, though this can affect the overall throughput of data.
Note that WDS implementation can vary from product to product. Hence 
there is no guarantee that different products will interoperate. In 
addition, the security settings for WDS links should be the same as the 
one setup for your wireless clients.
